Box 30772-00100, Nairobi, Kenya Received: 22 February 2017; revised: 30 May 2017 Accepted for publication: 1 June 2017; available online: ??? Summary – The yam nematode, Scutellonema bradys, is a major threat to yam (Dioscorea spp.) production across yam-growing regions. In West Africa, this species cohabits with many morphologically similar congeners and, consequently, its accurate diagnosis is essential for control and for monitoring its movement. In the present study, 46 Scutellonema populations collected from yam rhizosphere and yam tubers in different agro-ecological zones in Ghana and Nigeria were characterised by their morphological features and by sequencing of the D2-D3 region of the 28S rDNA gene and the mitochondrial COI genes. Molecular phylogeny, molecular species delimitation and morphology revealed S. bradys, S. cavenessi, S. clathricaudatum and three undescribed species from yam rhizosphere. Only S. bradys was identified from yam tuber tissue, however. For barcoding and identifying Scutellonema spp., the most suitable marker used was the COI gene.

Morphologically and molecularly characterization was carried out on five populations of Scutellonema paralabiatum, three populations of S. brachyurus, 2 populations of S. cavenessi, one unidentified Scutellonema species, 2 populations of Pratylenchus penetrans and P. goodeyi. Special emphasis was given to the description and characterization of a new Pratylenchus species. Pratylenchus n. sp. can be distinguished from the other Pratylenchus species by combination of the following features of female: body slender with medium size (469-600µm); body cuticle in lateral field with four lines at pharynx level and posteriorly at level of phasmid in tail region, six to eight lines at mid body and six to ten at vulva region; the lateral lines at vulva region showing a slight oblique pattern; ridges in general smooth except in some specimens at phasmid level where they are annulated. Labial region with 3 lips annuli, the last lip annulus thicker than the first two and offset by a deep constriction from the rest of the body, en face view showing no clear separation between subdorsal, subventral and lateral sectors.

  • Evaluation of Some Vulval Appendages in Nematode Taxonomy
    Comp. Parasitol. 76(2), 2009, pp. 191–209 Evaluation of Some Vulval Appendages in Nematode Taxonomy 1,5 1 2 3 4 LYNN K. CARTA, ZAFAR A. HANDOO, ERIC P. HOBERG, ERIC F. ERBE, AND WILLIAM P. WERGIN 1 Nematology Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected], [email protected]) and 2 United States National Parasite Collection, and Animal Parasitic Diseases Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected]) ABSTRACT: A survey of the nature and phylogenetic distribution of nematode vulval appendages revealed 3 major classes based on composition, position, and orientation that included membranes, flaps, and epiptygmata. Minor classes included cuticular inflations, protruding vulvar appendages of extruded gonadal tissues, vulval ridges, and peri-vulval pits. Vulval membranes were found in Mermithida, Triplonchida, Chromadorida, Rhabditidae, Panagrolaimidae, Tylenchida, and Trichostrongylidae. Vulval flaps were found in Desmodoroidea, Mermithida, Oxyuroidea, Tylenchida, Rhabditida, and Trichostrongyloidea. Epiptygmata were present within Aphelenchida, Tylenchida, Rhabditida, including the diverged Steinernematidae, and Enoplida. Within the Rhabditida, vulval ridges occurred in Cervidellus, peri-vulval pits in Strongyloides, cuticular inflations in Trichostrongylidae, and vulval cuticular sacs in Myolaimus and Deleyia. Vulval membranes have been confused with persistent copulatory sacs deposited by males, and some putative appendages may be artifactual. Vulval appendages occurred almost exclusively in commensal or parasitic nematode taxa. Appendages were discussed based on their relative taxonomic reliability, ecological associations, and distribution in the context of recent 18S ribosomal DNA molecular phylogenetic trees for the nematodes.

    BIOLOGY AND MANAGEMENT OF Meloidogyne incognita (KOFOID &WHITE, 1919) CHITWOOD, 1949 ON Cucumis sativus L. USING CROP ROTATION BY BUKOLA RUKAYAH AMINU-TAIWO B. Agric (Hons) (Ilorin), M. Sc., M. Phil. (Ibadan) A thesis in the Department of Crop Protection and Environmental Biology, Submitted to the Faculty of Agriculture and Forestry in partial fulfillment of the requirement for the Degree of DOCTOR OF PHILOSOPHY of the UNIVERSITY OF IBADAN National Horticultural Research Institute, Jericho, Idi-Ishin, Ibadan, Oyo State August, 2017 i ABSTRACT Cucumis sativus (Cucumber) is an edible fruit vegetable grown for its nutritional and economic values, but root-knot nematodes such as Meloidogyne incognita (MI) constitute a major constraint to its production. Nematicides, the most effective control option, are expensive and not environment friendly. Cultural practices such as crop rotation could reduce nematode infection but its effect on MI on cucumber has not been adequately documented. Therefore, biology, pathogenicity and management of Meloidogyne incognita with crop rotation were investigated. A survey of plant-parasitic nematodes on cucumber in Lagos, Ogun, Osun, Oyo, Kaduna and Plateau States where cucumber is mostly cultivated was carried out using systematic sampling technique. Pathogenicity of M. incognita on Marketer, Ashley, Tokyo and Marketmore varieties of cucumber were assessed in pot and field experiments. Sixty-four one week-old seedlings of each variety was inoculated at four inoculum densities: 0, 10,000, 20,000 and 40,000 eggs of MI in pots (20 kg soil) using a 4x4 factorial arrangement in a completely randomised design in four replicates. On the field, split-plot design was used with main plots (nematode-infested and nematode-free) and sub-plots (cucumber varieties).

Nematode sampling Unlike some pests and diseases, nematodes cannot be monitored by observation in the field. Nematodes must be extracted for microscopic examination in the laboratory. Nematodes can be collected by sampling soil and plant materials. There is no problem in finding nematodes, but getting the species and numbers you want may be trickier. In general, natural and undisturbed habitats will yield greater diversity and more slow-growing nematode species, while temporary and/or disturbed habitats will yield fewer and fast- multiplying species. Sampling considerations Getting nematodes in a sample that truly represent the underlying population at a given time requires due attention to sample size and depth, time and pattern of sampling, and handling and storage of samples.
